ADD connect failover

Question

Hi,
Is it the correct approach to set up a second Azure AD connect in an environment for high availability? Export the primary server configuration and configure the second server using this configuration file. By putting the second server in staging mode, we can ensure that it is ready when needed. When the time comes, we can simply take it out of staging mode.

Thanks

Answer 1

Yes. However, be sure to swap them (set staging on the primary - then set the new as prod) and test to ensure its working as expected. Think of them as peers not primary and backup. Any one of them could be active at any one time. The key is that only one can be at a time :)

Answer 2

@Shahin Mortazave Thank you for reaching out to us, Yes having a another Azure AD Connect server in staging mode is right approach and staging mode can be used for several scenarios, including:

• High availability.
• Test and deploy new configuration changes.
• Introduce a new server and decommission the old.

More information related to staging server has been documented here : https://learn.microsoft.com/en-us/azure/active-directory/hybrid/connect/how-to-connect-sync-staging-server#:~:text=your%20production%20environment.-,Staging%20mode,-Staging%20mode%20can

Yes you are right, whenever the primary Azure AD Connect server requires maintenance, you can use your staging server for production, by reconfiguring it via wizard.

Let me know if you have any further questions, feel free to post back.
